To evaluate the reliability and user experiences of an automated telephone system to monitor falls during a prolonged period of time.
Prospective cohort study.
Four neurological outpatient clinics in the Netherlands.
One hundred nineteen community-dwelling people with Parkinson's disease without dementia, because falls are common in this population.
Clinical and demographic data were obtained. The Falls Telephone is a computerized telephone system through which participants can enter the number of falls during a particular period. During a follow-up of 1 to 40 weekly calls, 2,465 calls were made. In total, 173 no-fall entries and 115 fall entries were verified using personal telephone interviews. User experiences were evaluated in 90 of the 119 participants using structured telephone interviews.
All no-fall entries and 78% of fall entries were confirmed to be correct. Sensitivity to detect falls was 100%, and specificity was 87%. Users regarded the Falls Telephone as a convenient tool to monitor falls.
The Falls Telephone is a convenient and reliable instrument to monitor falls. The automated system has high specificity, obviating the need for time-consuming personal follow-up calls in the majority of nonfallers. As such, the Falls Telephone lends itself well to data collection in large trials with prolonged follow-up in participants with Parkinson's disease.
评估一种自动化电话系统在长时间内监测跌倒的可靠性和用户体验。
前瞻性队列研究。
荷兰的 4 个神经科门诊。
119 名居住在社区的帕金森病但无痴呆患者，因为该人群中跌倒很常见。
收集临床和人口统计学数据。Falls Telephone 是一种计算机化的电话系统，通过该系统，参与者可以输入特定时间段内的跌倒次数。在 1 至 40 周的每周电话随访中，共进行了 2465 次通话。总共使用个人电话访谈验证了 173 次无跌倒记录和 115 次跌倒记录。在 119 名参与者中的 90 名参与者中使用结构化电话访谈评估了用户体验。
所有无跌倒记录和 78%的跌倒记录均被证实正确。检测跌倒的敏感性为 100%，特异性为 87%。用户认为 Falls Telephone 是监测跌倒的便捷工具。
Falls Telephone 是一种方便可靠的监测跌倒的工具。自动化系统具有较高的特异性，在大多数非跌倒者中无需进行耗时的个人随访电话。因此，Falls Telephone 非常适合在帕金森病患者中进行长时间随访的大型试验中的数据收集。
